Clear Frosted Glass Bottle, Glossy Silver Dropper, 15 ml

The 15 ml glass bottle with dropper is used for filling and dispensing liquid cosmetic products drop by drop. It is suitable for facial serums, facial and nail oils, blends of essential oils in a carrier oil, oil-based hair or beard elixirs, or for samples of larger recipes. Frosted glass dims the incoming light while keeping the liquid level visible, so you can see how much product remains in the bottle. The silver glossy dropper complements the matte surface of the glass, and the finished product looks cohesive even without further finishing.

The set consists of a bottle and a dropper with the same 18/410 neck finish. Both parts are declared suitable for contact with cosmetics.

What the set is suitable for

• Oil-based facial serums – the dropper dispenses the small amounts commonly used with serums, without spilling.
• Blends of essential oils in a carrier oil – massage and aromatherapy blends where the number of drops matters.
• Oils for nails, beard or hair ends – a small pack is used up before the oil starts to lose quality.
• Samples and test batches – 15 ml is enough to try out a recipe or as a gift size.
• Water-based serums and toners for spot application – the glass withstands both water-based and alcohol-based contents, but for water-based recipes you need to factor in a preservative.

How the dropper dispenses and seals

The dropper consists of a glass tube that reaches into the bottle, a silicone bulb for drawing up the liquid, a silver aluminium shell and a threaded PP plastic ring. Squeezing the bulb draws the contents into the tube, and they are released drop by drop directly onto the skin or into the palm. The thread of the ring seats on the neck of the bottle and closes it. When hand-tightened, the dropper holds securely during normal storage in an upright position. In a handbag or backpack, carry the bottle upright; the droppers are not designed to be left lying in the liquid for long.

Nominal and total volume

The nominal volume of 15 ml is the quantity the bottle is intended for in normal filling. The brimful capacity is the physical volume up to the neck. The difference is a reserve into which the dropper tube is inserted when closing, and also space for the contents to expand when the temperature changes. The bottle is therefore filled up to the nominal volume, not to the brim. If it is overfilled, part of the contents is pushed out through the thread when the dropper is inserted.

Good to know

Before the first filling, wash both the bottle and the dropper, disinfect them with isopropyl alcohol or ethanol and leave them to dry completely. Residual water in the glass tube would get into oil-based contents.

Glass does not react with oils, alcohol or water-based solutions, so the bottle can be reused after thorough washing. The weaker point is the silicone bulb. Concentrated essential oils or alcoholic tinctures may soften it over time or change its elasticity. For recipes with a high proportion of essential oils, check the bulb after several weeks.

At the end of its life, the glass bottle belongs in glass recycling. The dropper is combined packaging made of glass, plastic, aluminium and silicone. Before disposal, take it apart and sort the individual parts by material.
